Proportional dividers are used by many artists. Many people think proportional dividers are just used by architects. I am sure that you would find proportional dividers in the studio of many great artists.
A proportional divider is a tool that will check the accuracy of your drawing. It is a great tool for beginner artists and realism artists.
Proportional Dividers for Drawing
Same Size Reference Photo
If your drawing is going to be the same size as your reference photo, the proportional divider tool will easily show you if your proportions are correct.
All you have to do is measure the reference image against your drawing. If there is something that just does not look correct, check the dimensions with the divider. A lines width could make something look off.
The proportional divider is also a helpful tool if you use the grid method.
Double check your work with the proportional divider after you have drawn the contour of your subject. The grid will give you a starting point for your measurements. You will be able to easily check smaller sections using the grid method.
It is a good idea to check your work as you go along. It is much easier to fix a mistake early on, rather than when you are done with the drawing.
Enlarging an Image
The proportional tool is also very helpful if you would like to draw the reference larger than the photo.
There will be a larger opening on one side of the divider that you will be able to adjust. The larger opening and the smaller opening are proportioned to each other. This will allow your drawing to be accurate when you change the size.
